The Board of Public Works and Safety is authorized to investigate portions of any city street in the proximity of schools, churches, auditoriums, civic centers, kindergartens, theatres, and any other places where large numbers of people gather. If the Board determines that, within any part of any street, large numbers of pedestrians walk on or across the same and are exposed to serious traffic hazards by any vehicle operated in the street at usual speeds, the Board, by order, or the police in any temporary emergency, may declare and establish a special speed limit at such places.
